Abstract
The invention belongs to the field of cement concrete bridge deck pavement and discloses asphaltic sands and a waterproof leveling connection layer structure with asphalt sands; the structure is characterized by providing a mixture designing method of the asphaltic sands, a reasonable combination and the corresponding construction technique of the asphaltic sands and hot high viscous asphalt sealing, and the waterproof leveling connection layer structure which is good in waterproof effect, high in leveling, strong in interlayer connection force can be obtained. The waterproof leveling connection layer structure of the invention can be widely applied for the pavement fields of various road surfaces and bridge surfaces.
Description
Technical field
The present invention relates to the cement concrete bridge deck field of mating formation, also can be applicable to cement concrete pavement and tunnel road surface overlay field etc.Specifically a kind of water-proof leveling binder course.
Background technology
In the road and bridge pavement process, water-repellancy, the planarization controlling quality of the layer of mating formation concerning the work-ing life of the layer of mating formation.Aspect water-repellancy, especially for cement concrete bridge deck, if do not take into full account the waterproof effect of paving structure system, moisture content infiltrates through the laminar surface of mating formation mats formation between layer and the bridge floor, will speed up peeling off of mat formation layer and bridge floor; On the other hand, infiltrate the moisture content of mating formation between layer and the bridge floor, will further infiltrate in bridge floor and the girder construction, cause the steel bar corrosion of structure, also can produce freeze-thaw damage, cause the degradation of bridge structure, have influence on the weather resistance of bridge at extremely frigid zones.And aspect planarization,, be prone to cause road surface, deck paving planeness to descend, the comfortableness of influence driving because the road and bridge of traditional method construction lack necessary levelling structural sheet in the paving structure; And vehicle jolts in the process of going, and the travelling load of road pavement, bridge floor impacts and increases, and has also quickened the destruction of paving structure.
Summary of the invention
Technical assignment of the present invention is the deficiency to above-mentioned prior art, and a kind of water-proof leveling binder course is provided.
Technical assignment of the present invention is realized by following mode: through the tar sand raw material being carried out strict grating design; Obtain water-proof leveling obvious results tar sand; Through with the reasonable combination and the corresponding construction technology of hot high-viscosity asphalt seal, obtain a kind of good water-proof effect, planeness is high, the interlayer connecting forces is strong water-proof leveling binder course structure.This structure not only has significant water-proof leveling effect, and helps strengthening and the mat formation connection of layer of cement concrete bridge deck and asphalt.
The making technology of water-proof leveling binder course is:
A, treat the processing aspect cut a hole the hair, clean;
After b, the pending aspect drying, hot high-viscosity asphalt seal processing is carried out on the surface above that, is specially:
B-1, be spread on the pending aspect with the high-viscosity asphalt of road oiler with 170 ℃～180 ℃, the spreading layer thickness is 0.8～1.2mm;
B-2, spreading one deck particle diameter is the rubble of 5～10mm on above-mentioned high-viscosity asphalt spreading layer, and said rubble is with 3～5% pitch premixing;
B-3, rubble is rolled stable with pneumatic-tired rollers; Perhaps, with blowtorch that the rubble baking is stable;
C, accomplish above-mentioned hot high-viscosity asphalt seal and handle after, making asphaltic sands immediately, tar sand adopts heavy pneumatic-tired rollers compacting 3-4 time, uses dual-steel wheel road roller compacting, pressing then, the making thickness of asphaltic sands is 2cm, voidage is 4-8%,
The grading limit of said tar sand is:
9.5mm?100％～100％ 4.75mm?95％～100％
2.36mm?60％～70％ 1.18mm?40％～50％
0.6mm?21％～39％ 0.3mm?11％～29％
0.15mm?8％～16％ 0.075mm?6％～9％。
Among the step c, the voidage of asphaltic sands is preferably 4-6% after the compacting.
The present invention compared with prior art has following outstanding beneficial effect:
(1) the tar sand structure that adopts has the effect of excellent waterproof, levelling; Reduce the thickness deviation of road surface, bridge deck pavement, improved the planeness of the layer of mating formation, not only strengthened the connection of asphalt mixture surfacing and cement concrete bridge deck; Simultaneously; After the construction of the bearing stratum on tar sand upper strata, compound can embed in the tar sand structural sheet, can enhancement layer between the connection ability;
(2) hot high-viscosity asphalt seal not only plays the waterproof layer effect, and the interlayer that can also strengthen between pending and the water-proof leveling binder course connects;
(3) asphaltic sands is used in combination with hot high-viscosity asphalt; Increase the bond strength between bearing stratum and pending to greatest extent, guaranteed water resistance well, avoided the infiltration of moisture content; Improve road surface deck paving quality; Can improve the use properties that asphalt is mated formation, reduce disease and take place, prolong the work-ing life of road surface bridge deck pavement and bridge.
